WILLIAM E. VERNON, OF OSKALOOSA, IOWA.

MACHINE FOR RQASTINGCOFFEE, PEANUTS, 8L0.

SPECIFICATION forming part of Letters Patent No. 240,867, dated May 3,1881.

To all whom it may concern:

Be it known that I, WILLIAM E. VERNON, of Oskaloosa, in the county ofMahaska and State of Iowa, have invented certain new and usefulImprovements in Machines for Roasting Coffee, Peanuts, and the Like; andI do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

Figure 1 is a perspective view. Fig. 2 is a vertical sectional viewtaken longitudinally through the cylinder. Fig. 3 is a verticalcross-section. Fig. 4 is a perspective detail view, showingthe cylinderin position for discharging its contents; and Fig. 5 is a detail view ofthe testing-spoon and plug.

Corresponding parts in the several figures are denoted by like lettersof reference.

This invention relates to machines for roasting coffee, peanuts, and thelike, and for popping corn; and it consists in certain improvements inthe construction of the same, which will be hereinafter fully described,and particularly pointed out in the claim.

In the drawings hereto annexed, A represents a suitable chamber orframe, provided at one end with a half-casing, B, formed of twocast-metal heads, 0 0, connected by rods 7 D D, and spaced by the curvedside pieces, E E, which form, with the said heads, a near- 1ysemi-cylindrical but bottomless bed or casing, (represented by theletterB,) as above set forth.

The heads 0 (J are provided with bearings F, for the tubular axis orstub-axles G of a drum or cylinder, H. The latter consists of thebody I,provided with double heads J, and With a laterally and longitudinallysliding cover, K, through which it may be filled with the coffee or nutsto be roasted, or its contents discharged, as the case may be.

The cylinder-axles G are provided with pivoted arms L, pivoted also tothe front rod D, by which the heads 0 O are connected, thus enabling thecylinder to be thrown forward to the position shown in Fig. 4.-

M M are arms pivoted upon the axles G, and

provided with curved slots N, by which they slide upon studs 0, fixedupon the inner sides Application filetl'February 26, 1881. (ModeL) ofthe heads 0, as shown, and forming combined guides and stops for thecylinder.

P is a semi-cylindrical cover, hinged upon 5 the rear rod D, andprovided with a .perforated slide or damper, Q, by means of which aseries of ventilating-openings, R, formed in the top of the said covermay be opened or closed at pleasure.

The openings of the tubular axles G are closed by means of tubularscoops S, hav'ing plugs T, which form combined stoppers and handles.

In the chamber or frame A is arranged a suitable motor, U, from whichmotion is con veyed, by means of a belt or band, V, to theroasting-cylinder, one of the axles G of which is provided with a drumor pulley, W, for this purpose.

A charcoal-furnace, or a series of gasolinejets, or any other suitableheating device, is to be arranged under the roasting-cylinder for thepurpose of roasting its contents.

Upon the sides of the frame A are formed ledges X, to support asuitably-constructed cooling-pan, Y, which may be readily removed whendesired, and which is preferably provided with a slanting front, side,or spout, Z.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of my invention will bereadily understood. The condition of the contents of theroasting-cylinder may be at any time readily ascertained by removing aportion thereof by means of one of the scoops S, which may be readilydone while the cylinder is in motion.

Having thus described my invention, I claim and desire to secure byLetters Patent 0 of the United States The combination, with thesemi-casing B, of the roasting-cylinder H, having axles Gr, pivoted armsL, and arms M, having curved slots N, substantially as and for thepurpose set 5 forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

WILLIAM ELIAS VERNON.
